Description

本発明は、開口部の吊元側に回転自在に支持される戸パネルに関する。   The present invention relates to a door panel that is rotatably supported on a hanging side of an opening.

従来より、無垢材等からなる戸パネルに比べて軽量化が図れることから、芯材に面材を貼着した構成とされたいわゆるフラッシュパネル状の戸パネルが知られている。このような芯材を構成する縦桟材は、木質系材料から形成されているため、反りが生じ易く、戸パネル自体に反りが生じ易くなるという問題があった。
例えば、下記特許文献１には、矩形状に枠組みされた左右の縦枠部及び上下の横枠部を備えたパネル枠の両面に外面板を設けたフラッシュパネルが開示されている。また、このフラッシュパネルは、縦枠部を構成する複数本の縦桟のうちの内縦桟に、横断面形状が側方に開口した溝形の補強金属板を被せた構成とされている。 2. Description of the Related Art Conventionally, a so-called flash panel-like door panel having a structure in which a face material is attached to a core material is known because the weight can be reduced as compared with a door panel made of a solid material or the like. Since the vertical beam members constituting such a core material are formed of a wood-based material, there is a problem that warpage is likely to occur and warpage is likely to occur in the door panel itself.
For example, Patent Document 1 below discloses a flash panel in which outer plates are provided on both sides of a panel frame having left and right vertical frame portions and upper and lower horizontal frame portions that are framed in a rectangular shape. In addition, the flash panel is configured such that a groove-shaped reinforcing metal plate whose lateral cross-sectional shape opens laterally is covered on an inner vertical rail among a plurality of vertical rails constituting the vertical frame portion.

特開２０１４−１０９１１５号公報JP 2014-109115 A

しかしながら、上記のようなフラッシュパネルを比較的に戸高寸法が大とされた開き戸（ハイドア）として用いる場合には、ハンドル及びラッチ部がパネルの下端側に寄った位置に設けられることとなる。そのため、閉鎖された際に戸先側端部の上端側が振動（びびり振動）し易くなり、異音が生じ易くなることが考えられる。つまり、閉鎖側に移動するパネルのラッチ部がラッチ受に挿入されてパネルが戸当たりに当接すれば、パネルの戸先側のラッチ部から離れた部位が戸当たりに対して跳ね返りと当接とを繰り返すように戸厚方向に振動する傾向がある。このような振動は、ラッチ部の下側部位よりも長尺状となる上側部位において顕著になることが考えられ、更なる改善が望まれる。   However, when the flash panel as described above is used as a hinged door (high door) having a relatively large door height, the handle and the latch portion are provided at a position close to the lower end side of the panel. Therefore, it is considered that the upper end side of the door end side end portion is likely to vibrate (chatter vibration) when closed and abnormal noise is likely to occur. In other words, if the latch part of the panel moving to the closing side is inserted into the latch receiver and the panel comes into contact with the door stop, the part away from the latch part on the door end side of the panel will rebound and contact with the door stop. Tends to vibrate in the door thickness direction. Such vibration is considered to be prominent in the upper part that is longer than the lower part of the latch portion, and further improvement is desired.

本発明は、上記実情に鑑みてなされたものであり、軽量化が図れ、反りの抑制が可能でありながらも、閉鎖させる際に生じる異音を低減し得る戸パネルを提供することを目的としている。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a door panel that can reduce weight and can suppress warping, but can reduce abnormal noise generated when closing. Yes.

上記目的を達成するために、本発明に係る戸パネルは、木質系材料から形成された縦桟材を有したパネル芯材の戸厚方向両側に面材が設けられ、開口部の吊元側に回転自在に支持される戸パネルであって、戸高方向中央よりも下方側に位置するように、戸先側端部に組み込まれたラッチ部と、前記縦桟材が嵌め込まれる凹溝が戸幅方向に開口するように設けられた金属製の補強材と、を備えており、前記補強材は、長さ寸法が戸高寸法よりも小とされ、かつ下端側に片寄るように設けられていることを特徴とする。   In order to achieve the above object, a door panel according to the present invention is provided with a face material on both sides in the door thickness direction of a panel core material having a vertical crosspiece formed of a wood-based material, and a suspension base side of an opening. The door panel is rotatably supported by the door, and includes a latch portion incorporated in the door end side end portion so as to be located below the center of the door height direction, and a concave groove into which the vertical beam member is fitted. A metal reinforcing material provided so as to open in the width direction, and the reinforcing material is provided so that the length dimension is smaller than the door height dimension and the lower end side is offset. It is characterized by that.

本発明に係る戸パネルは、上述のような構成としたことで、軽量化が図れ、反りの抑制が可能でありながらも、閉鎖させる際に生じる異音を低減することができる。   Since the door panel according to the present invention is configured as described above, the weight can be reduced and the warpage can be suppressed, but the noise generated when the door is closed can be reduced.

In some of the drawings, some of the detailed reference numerals attached to other drawings are omitted.
In the following embodiments, directions such as the vertical direction will be described with reference to a state in which the door panel according to each embodiment is constructed.

図１〜図３は、第１実施形態に係る戸パネルの一例を模式的に示す図である。
本実施形態に係る戸パネル１は、パネル芯材１０のパネル厚さ方向両側に面材２７を設けた構成とされている。このような構成とすれば、無垢材等によって中実板状とされたものと比べて、軽量化を図ることができる。つまり、戸パネル１は、中実板状ではなく、中空状のパネル芯材１０のパネル厚さ方向両側に面材２７を設けたいわゆるフラッシュパネル状とされている。
また、戸パネル１は、住居等の建物に設けられ出入口等となる開口部の吊元側に回転自在に支持されて開き戸を構成する。 1-3 is a figure which shows typically an example of the door panel which concerns on 1st Embodiment.
The door panel 1 according to the present embodiment has a configuration in which face members 27 are provided on both sides of the panel core member 10 in the panel thickness direction. With such a configuration, the weight can be reduced as compared with a solid plate made of solid material or the like. That is, the door panel 1 is not a solid plate shape but a so-called flash panel shape in which the face members 27 are provided on both sides of the hollow panel core member 10 in the panel thickness direction.
Moreover, the door panel 1 is rotatably supported by the suspension side of the opening part which is provided in buildings, such as a residence, and becomes an entrance / exit etc., and comprises a hinged door.

この戸パネル１は、図１（ａ）及び図２（ａ）に示すように、一方向（上下方向）に長尺な略矩形平板状とされている。
この戸パネル１の戸高寸法（長さ寸法）Ｈ１は、当該戸パネル１によって開閉される開口部の開口高に応じた寸法であればよく、標準的な戸高寸法Ｈ１、例えば、１８００ｍｍ〜２１００ｍｍ程度でもよい。また、戸パネル１は、戸高寸法Ｈ１が天井高と略同高さ、例えば、２４００ｍｍ〜３０００ｍｍ程度とされたハイドアを構成するものでもよい。また、戸パネル１の戸幅（パネル幅）寸法は、開口部の開口幅に応じた寸法であればよく、６００ｍｍ〜１２００ｍｍ程度でもよい。また、戸パネル１の戸厚（パネル厚）寸法は、２０ｍｍ〜４０ｍｍ程度でもよい。 As shown in FIGS. 1A and 2A, the door panel 1 has a substantially rectangular flat plate shape that is long in one direction (vertical direction).
The door height dimension (length dimension) H1 of the door panel 1 may be a dimension corresponding to the opening height of the opening that is opened and closed by the door panel 1, and is a standard door height dimension H1, for example, about 1800 mm to 2100 mm. But you can. Moreover, the door panel 1 may constitute a high door whose door height dimension H1 is substantially the same as the ceiling height, for example, about 2400 mm to 3000 mm. Moreover, the door width (panel width) dimension of the door panel 1 should just be a dimension according to the opening width of an opening part, and may be about 600 mm-1200 mm. The door thickness (panel thickness) dimension of the door panel 1 may be about 20 mm to 40 mm.

また、この戸パネル１の戸先側端部には、開口部の戸先側縦枠等に設けられるラッチ受（ストライク）に挿入されるラッチ部３が組み込まれている。このようなラッチ部３としては、戸パネル１の戸先側端部に埋込状に設けられたラッチ錠装置２に対して戸幅方向（パネル幅方向）に出没自在とされたラッチボルトのラッチ頭部でもよい。また、図１（ａ）では、図示を省略しているが、戸パネル１の戸先側端部の戸厚方向両側には、ラッチ錠装置２に連結されてラッチ部３を出没させるハンドルが設けられる。このようなハンドルとしては、レバー状のものや、握玉状のもの、いわゆるプッシュプルハンドル等でもよい。また、ラッチ錠装置２としては、公知のものの採用が可能であり、ラッチ部３の没入を阻止するロック機構を有したものやデッドボルトを出没させるサムターンを備えたものでもよい。   Moreover, the latch part 3 inserted in the latch receptacle (strike) provided in the door-end side vertical frame etc. of an opening part is integrated in the door-end side edge part of this door panel 1. As shown in FIG. As such a latch portion 3, a latch bolt that can be protruded and retracted in the door width direction (panel width direction) with respect to the latch lock device 2 embedded in the door end side end portion of the door panel 1 is used. A latch head may be used. Although not shown in FIG. 1 (a), handles that are connected to the latch lock device 2 and project the latch portion 3 on both sides in the door thickness direction of the door end side portion of the door panel 1 are shown. Provided. Such a handle may be a lever-shaped one, a handball-shaped one, a so-called push-pull handle, or the like. Further, as the latch lock device 2, a known device can be adopted, and a device having a lock mechanism for preventing the latch portion 3 from entering and a device having a thumb turn for retracting the dead bolt may be used.

また、ラッチ部３は、戸高方向（パネル長手方向）中央ＣＬよりも下方側に位置するように設けられている。つまり、戸パネル１の下端面からラッチ部３（ラッチ部３の上下方向中心（ラッチセンター））までの戸高方向に沿うラッチ下方側高さ寸法Ｈ２よりも戸パネル１の上端面からラッチ部３までの戸高方向に沿うラッチ上方側高さ寸法Ｈ３が大とされている。ラッチ下方側高さ寸法Ｈ２は、ラッチ錠装置２に連結されるハンドルの高さが操作し易い高さとなるように、適宜の高さとしてもよく、例えば、８００ｍｍ〜１０００ｍｍ程度でもよく、好ましくは、８５０ｍｍ〜９５０ｍｍ程度でもよい。また、ラッチ上方側高さ寸法Ｈ３は、上記した戸パネル１自体の戸高寸法Ｈ１やラッチ下方側高さ寸法Ｈ２に応じて適宜の寸法としてもよい。図例では、ラッチ上方側高さ寸法Ｈ３を、ラッチ下方側高さ寸法Ｈ２の１．９倍程度とした例を示している。
なお、戸パネル１の吊元側端部に、開口部の吊元側縦枠等に固定される蝶番等の回転連結部材を受け入れる凹所を設けた構成としてもよい。 Moreover, the latch part 3 is provided so that it may be located below the door height direction (panel longitudinal direction) center CL. That is, the latch portion 3 from the upper end surface of the door panel 1 is higher than the latch lower height dimension H2 along the door height direction from the lower end surface of the door panel 1 to the latch portion 3 (the vertical center of the latch portion 3 (latch center)). The height H3 of the latch upper side along the door height direction is made large. The latch lower side height dimension H2 may be set to an appropriate height so that the handle connected to the latch lock device 2 is easily operated, for example, about 800 mm to 1000 mm, preferably About 850 mm to 950 mm. The latch upper side height dimension H3 may be an appropriate dimension according to the door height dimension H1 of the door panel 1 itself or the latch lower side height dimension H2. In the example shown in the figure, the latch upper side height dimension H3 is about 1.9 times the latch lower side height dimension H2.
In addition, it is good also as a structure which provided the recess which receives rotation connection members, such as a hinge fixed to the suspension side edge part of the door panel 1 at the suspension side vertical frame etc. of the opening part.

パネル芯材１０は、図１（ｂ）に示すように、枠体を構成する四周枠１１を有している。
四周枠１１は、上端部に設けられた上横枠部１２と、戸幅方向両側に対状に設けられた両側の縦枠部１３，１３と、下端部に設けられた下横枠部１６と、を備えている。また、本実施形態では、四周枠１１内に、複数の桟材１７，１８，１９，２０と、コア材２６と、を設けた構成としている。四周枠１１を構成する各枠部１２，１３，１３，１６、複数の桟材１７，１８，１９，２０及びコア材２６の戸厚方向に沿う寸法は、互いに略同寸法とされている。 As shown in FIG. 1B, the panel core member 10 has a four-round frame 11 constituting a frame body.
The quadrilateral frame 11 includes an upper horizontal frame portion 12 provided at the upper end portion, vertical frame portions 13 and 13 on both sides provided in pairs on both sides in the door width direction, and a lower horizontal frame portion 16 provided at the lower end portion. And. In the present embodiment, a plurality of crosspieces 17, 18, 19, 20 and a core material 26 are provided in the four-circumferential frame 11. The dimensions along the door thickness direction of the frame portions 12, 13, 13, 16, the plurality of crosspieces 17, 18, 19, 20 and the core material 26 constituting the quadrilateral frame 11 are substantially the same.

上横枠部１２は、戸幅方向に延びるように長尺状とされている。本実施形態では、上横枠部１２の下方側に戸幅方向に延びるように長尺状とされた横桟材を設けた構成としている。また、上横枠部１２の下方側に複数（図例では、３本）の横桟材を積み重ねるように設けた構成としている。これら横桟材を含んで上横枠部１２として把握するようにしてもよい。つまり、上横枠部１２を、複数の横桟材を戸高方向に隣接させて接合した構成としてもよい。このような構成とすれば、上横枠部１２の剛性を効果的に向上させることができ、反りや変形等を抑制することができる。また、上横枠部１２を、パネル芯材１０の上端部に埋込状に設けられる種々の部材の下地として利用したり、戸高寸法Ｈ１の調整代として利用したりすることもできる。   The upper horizontal frame portion 12 is elongated so as to extend in the door width direction. In this embodiment, it is set as the structure which provided the horizontal crosspiece made into the elongate shape so that it might extend in the door width direction below the upper horizontal frame part 12. As shown in FIG. In addition, a plurality of (three in the illustrated example) horizontal rail members are stacked on the lower side of the upper horizontal frame portion 12. You may make it grasp | ascertain as the upper horizontal frame part 12 including these horizontal crosspieces. That is, the upper horizontal frame portion 12 may have a configuration in which a plurality of horizontal crosspieces are adjacently joined in the door height direction. With such a configuration, the rigidity of the upper horizontal frame portion 12 can be effectively improved, and warpage, deformation, and the like can be suppressed. Further, the upper horizontal frame portion 12 can be used as a base for various members provided in an embedded manner at the upper end portion of the panel core member 10, or can be used as an adjustment allowance for the door height dimension H1.

下横枠部１６は、戸幅方向に延びるように長尺状とされている。本実施形態では、上横枠部１２と概ね同様、下横枠部１６の上方側に戸幅方向に延びるように長尺状とされた横桟材を設けた構成としている。図例では、下横枠部１６の上方側に１本の横桟材を設けた例を示しているが、複数の横桟材を積み重ねるように設けた構成としてもよい。また、横桟材を含んで下横枠部１６として把握するようにしてもよい。つまり、下横枠部１６を、複数の横桟材を戸高方向に隣接させて接合した構成としてもよい。この下横枠部１６を構成する横桟材及び上横枠部１２を構成する横桟材の戸高方向に沿う幅寸法は、互いに略同寸法とされている。
また、本実施形態では、これら上下の横枠部１２，１６と両側の縦枠部１３，１３とをいわゆる縦勝状に接合した構成としている。つまり、両側の縦枠部１３，１３の上端部及び下端部の互いに向き合う内側面に上横枠部１２及び下横枠部１６の長手方向の各端面を当接させ、これら上下の横枠部１２，１６と両側の縦枠部１３，１３とを接合した構成としている。なお、上横枠部１２及び下横枠部１６を構成する横桟材同士及び上下の横枠部１２，１６と両側の縦枠部１３，１３とは、ステープル（いわゆるＵ針）等の止具６（図２（ｂ）参照）や接着剤等を用いて接合されたものでもよい。 The lower horizontal frame portion 16 is elongated so as to extend in the door width direction. In the present embodiment, in the same manner as the upper horizontal frame portion 12, a horizontal beam member that is elongated so as to extend in the door width direction is provided on the upper side of the lower horizontal frame portion 16. In the example of the figure, an example is shown in which one horizontal crosspiece is provided on the upper side of the lower horizontal frame portion 16, but a configuration in which a plurality of horizontal crosspieces are stacked may be employed. Moreover, you may make it grasp | ascertain as the lower horizontal frame part 16 including a horizontal crosspiece. That is, the lower horizontal frame portion 16 may be configured by joining a plurality of horizontal crosspieces adjacent to each other in the door height direction. The width dimensions along the door height direction of the horizontal crosspieces constituting the lower horizontal frame portion 16 and the horizontal crosspieces constituting the upper horizontal frame portion 12 are substantially the same.
In the present embodiment, the upper and lower horizontal frame portions 12 and 16 and the vertical frame portions 13 and 13 on both sides are joined in a so-called vertical shape. That is, the longitudinal end surfaces of the upper horizontal frame portion 12 and the lower horizontal frame portion 16 are brought into contact with the mutually facing inner surfaces of the upper and lower ends of the vertical frame portions 13 and 13 on both sides, and these upper and lower horizontal frame portions are brought into contact with each other. 12 and 16 and the vertical frame portions 13 and 13 on both sides are joined. The horizontal crosspieces constituting the upper horizontal frame portion 12 and the lower horizontal frame portion 16 and the upper and lower horizontal frame portions 12, 16 and the vertical frame portions 13, 13 on both sides are fixed to staples (so-called U needles) or the like. What was joined using the tool 6 (refer FIG.2 (b)), an adhesive agent, etc. may be used.

両側の縦枠部１３，１３は、戸高方向に延びるように長尺状とされている。本実施形態では、これら両側の縦枠部１３，１３のうちの少なくとも一方の第１縦枠部１３，１３を、木質系材料から形成された２つの縦桟部１４，１５を戸幅方向に隣接させて接合した構成としている。このような構成とすれば、少なくとも一方の第１縦枠部１３，１３を、単一の縦桟材からなるものとした場合と比べて、剛性を効果的に向上させることができ、反りや変形等を抑制することができる。
また、２つの縦桟部１４，１５のうちの一方の第１縦桟部１４を、戸高方向一方側の長尺縦桟材１４ａと戸高方向他方側の短尺縦桟材１４ｂとを接合した構成としている。また、２つの縦桟部１４，１５のうちの他方の第２縦桟部１５を、戸高方向他方側の長尺縦桟材１５ａと戸高方向一方側の短尺縦桟材１５ｂとを接合した構成としている。 The vertical frame portions 13 and 13 on both sides are elongated so as to extend in the door height direction. In the present embodiment, at least one of the first vertical frame portions 13 and 13 of the vertical frame portions 13 and 13 on both sides is arranged with the two vertical beam portions 14 and 15 formed of a wood-based material in the door width direction. It is set as the structure joined adjacently. With such a configuration, the rigidity can be effectively improved as compared with the case where at least one of the first vertical frame portions 13 and 13 is made of a single vertical crosspiece, and warping and Deformation and the like can be suppressed.
Moreover, the structure which joined one 1st vertical beam part 14 of the two vertical beam parts 14 and 15 with the long vertical beam material 14a of the door height direction one side, and the short vertical beam material 14b of the door height direction other side. It is said. Further, the other second vertical beam portion 15 of the two vertical beam portions 14 and 15 is configured by joining a long vertical beam material 15a on the other side in the door height direction and a short vertical beam material 15b on the one side in the door height direction. It is said.

上記のような構成とすれば、各縦桟部１４，１５を、戸高寸法Ｈ１に応じた一本の長尺な縦桟材によって構成したものと比べて、２つの縦桟材１４，１５のうちの少なくとも一つ（例えば、長尺縦桟材）を戸高寸法Ｈ１の異なる複数の戸パネル１に対して適用することができ、長尺部材の共用化を図ることができる。また、比較的に戸高寸法Ｈ１が大とされた戸パネル１を構成する長尺部材の調達性を向上させることができ、このような戸パネル１を容易に実現することができる。また、各縦枠部１３，１３を構成する縦桟部１４，１５のそれぞれを、３本以上の縦桟材を備えた構成としたものと比べて、構造の簡略化が図れ、また、長尺縦桟材１４ａ，１５ａによって剛性を確保することができる。
また、第１縦桟部１４を、戸高方向一方側の長尺縦桟材１４ａと戸高方向他方側の短尺縦桟材１４ｂとを接合した構成とし、第２縦桟部１５を、戸高方向他方側の長尺縦桟材１５ａと戸高方向一方側の短尺縦桟材１５ｂとを接合した構成としている。このような構成とすれば、各縦桟部１４，１５のそれぞれの接合位置４，５が互いに戸高方向で異なる位置となり、例えば、接合位置４，５を戸高方向で同位置（同高さ位置）としたものと比べて、剛性が低下するようなことを抑制することができる。 If it is set as the above structures, compared with what constituted each vertical beam part 14 and 15 by one elongate vertical beam material according to the door height dimension H1, two vertical beam members 14 and 15 are provided. At least one of them (for example, a long vertical bar member) can be applied to a plurality of door panels 1 having different door height dimensions H1, and the long member can be shared. Moreover, the procurement property of the elongate member which comprises the door panel 1 by which the door height dimension H1 was made comparatively large can be improved, and such a door panel 1 can be implement | achieved easily. In addition, the structure of each of the vertical beam portions 14 and 15 constituting each vertical frame portion 13 and 13 can be simplified compared to a configuration in which three or more vertical beam members are provided. Rigidity can be ensured by the vertical bars 14a and 15a.
Further, the first vertical beam portion 14 is configured by joining the long vertical beam member 14a on one side of the door height direction and the short vertical beam member 14b on the other side of the door height direction, and the second vertical beam portion 15 is connected to the other side of the door height direction. The long vertical beam member 15a on the side and the short vertical beam member 15b on one side in the door height direction are joined together. With such a configuration, the joining positions 4 and 5 of the vertical beam portions 14 and 15 are different from each other in the door height direction.

Further, the length H4 of the reinforcing material 21 is made smaller than the door height dimension H1, and the reinforcing material 21 is provided so as to be offset toward the lower end side. With such a configuration, the door-end side end generated when closing the handle and the latch portion 3 can be positioned at an appropriate height in the door panel 1 having a relatively large door height dimension H1. The vibration at the upper end side of the part can be reduced, and the occurrence of abnormal noise can be reduced. That is, since the reinforcing material 21 having a relatively large specific gravity is provided so as to be offset toward the lower end side, the center of gravity of the door panel 1 is lowered as compared with the case where the reinforcing material 21 is provided so as to be offset toward the upper end side. be able to. Thereby, the vibration to the door thickness direction of the upper end side used as the site | part spaced apart from the latch part 3 of the door end side end part which becomes easy to produce when the door panel 1 is closed can be suppressed. That is, it can be reduced that the upper end side above the latch portion 3 of the door panel 1 moving to the closing side vibrates due to inertial force. Moreover, if the reinforcing material 21 is made shorter than the door height dimension H1, the reinforcing material 21 can be applied to a plurality of door panels 1 having different door height dimensions H1, for example. That is, by making the dimension (upper end side door height dimension) H6 of the upper part of the reinforcing material 21 of the door panel 1 different, the door panel having a different door height dimension H1 can be easily realized.

また、本実施形態では、縦桟材２０及びこれが嵌め込まれる補強材２１を、戸幅方向中央よりも戸先側に位置するように設けた構成としている。このような構成とすれば、戸パネル１の戸先側の反りを抑制することができる。また、戸幅方向中央部位や吊元側のみに補強材２１を設けたものと比べて、戸パネル１が閉鎖される際に生じる戸先側端部の上端側の戸厚方向への振動をより効果的に抑制することができる。
また、本実施形態では、縦桟材２０及びこれが嵌め込まれる補強材２１を、戸幅方向両側部位に設けた構成としている。このような構成とすれば、戸パネル１の戸幅方向両側の反りを抑制することができる。なお、戸先側の縦桟材２０及び補強材２１と吊元側の縦桟材２０及び補強材２１とは、互いに同様の構成であるので、以下では、一方を例にとって説明する。 Moreover, in this embodiment, it is set as the structure which provided the vertical crosspiece 20 and the reinforcing material 21 in which this is fitted so that it may be located in the door-end side rather than the door width direction center. If it is set as such a structure, the curvature at the door-end side of the door panel 1 can be suppressed. Moreover, compared with what provided the reinforcing material 21 only in the door width direction center site | part and the suspension base side, the vibration to the door thickness direction of the upper end side of the door end side edge produced when the door panel 1 is closed is carried out. It can suppress more effectively.
Moreover, in this embodiment, it is set as the structure which provided the vertical beam 20 and the reinforcing material 21 in which this is fitted in the door width direction both sides site | part. If it is set as such a structure, the curvature of the door width direction both sides of the door panel 1 can be suppressed. In addition, since the vertical beam member 20 and the reinforcing member 21 on the door end side and the vertical beam member 20 and the reinforcing member 21 on the hanging end side have the same configuration, description will be given below by taking one as an example.

縦桟材２０及び補強材２１は、戸高方向に延びるように長尺状とされている。
補強材２１の長さ寸法Ｈ４は、ラッチ部３の高さ等に応じて、また、反りを抑制する観点や軽量化を図る観点等から適宜の長さ寸法としてもよく、戸高寸法Ｈ１の３／５〜１７／２０程度の寸法としてもよい。図例では、補強材２１の長さ寸法Ｈ４を、上記した縦枠部１３の各縦桟部１４，１５の長尺縦桟材１４ａ，１５ａの長さ寸法Ｈ７と略同長さとし、戸高寸法Ｈ１の３／４程度の寸法とした例を示している。
また、下端側に片寄って設けられる補強材２１の高さ位置は、ラッチ部３の高さ等に応じて、適宜の高さ位置とすればよい。本実施形態では、補強材２１を長手方向に３等分した中央部がラッチ部３の高さとなるように補強材２１を設けた構成としている。つまり、戸幅方向に見て、ラッチ部３と補強材２１を長手方向に３等分した中央部とが重なり合う位置となるように補強材２１を設けた構成としている。 The vertical crosspiece 20 and the reinforcing member 21 are elongated so as to extend in the door height direction.
The length dimension H4 of the reinforcing member 21 may be an appropriate length dimension according to the height of the latch portion 3 or the like, or from the viewpoint of suppressing warpage or reducing the weight. It is good also as a dimension of about / 5-17 / 20. In the illustrated example, the length dimension H4 of the reinforcing member 21 is substantially the same as the length dimension H7 of the long vertical beam members 14a and 15a of the vertical beam portions 14 and 15 of the vertical frame portion 13 described above, and the door height dimension. An example in which the dimension is about 3/4 of H1 is shown.
In addition, the height position of the reinforcing member 21 provided to be offset toward the lower end side may be set to an appropriate height position according to the height of the latch portion 3 or the like. In the present embodiment, the reinforcing material 21 is provided so that the central portion obtained by dividing the reinforcing material 21 into three in the longitudinal direction is the height of the latch portion 3. In other words, the reinforcing member 21 is provided so that the latch portion 3 and the central portion obtained by dividing the reinforcing member 21 into three in the longitudinal direction overlap each other when viewed in the door width direction.

また、本実施形態では、補強材２１を、下横枠部１６との間に間隔を空けるように設けた構成としている。つまり、補強材２１を、戸パネル１の下端部近傍に至るまで設けずに、戸パネル１の下端側に補強材２１の存在しない部位を設けた構成としている。つまりは、本実施形態では、戸パネル１の上下両側に補強材２１の存在しない部位を設けた構成としている。補強材２１の下端から戸パネル１の下端面までの戸高方向に沿う下端側戸高寸法Ｈ５は、補強材２１の上端から戸パネル１の上端面までの戸高方向に沿う上端側戸高寸法Ｈ６よりも小とすればよい。この下端側戸高寸法Ｈ５は、上端側戸高寸法Ｈ６の１／２〜１／５程度の寸法としてもよい。   In the present embodiment, the reinforcing member 21 is provided so as to be spaced from the lower horizontal frame portion 16. In other words, the reinforcing material 21 is not provided until the vicinity of the lower end portion of the door panel 1, and a portion where the reinforcing material 21 does not exist is provided on the lower end side of the door panel 1. That is, in this embodiment, it is set as the structure which provided the site | part which does not exist the reinforcing material 21 in the upper and lower sides of the door panel 1. FIG.

Small. The lower end side door height dimension H5 may be about 1/2 to 1/5 of the upper end side door height dimension H6.

また、本実施形態では、縦桟材２０及び補強材２１の長さ寸法Ｈ４を、互いに略同寸法としている。つまり、縦桟材２０を、戸パネル１の全長に亘って設けずに、その長さ寸法Ｈ４を戸高寸法Ｈ１よりも小とし、かつ下端側に片寄らせて設けた構成としている。
また、縦桟材２０の上端部を、上横枠部１２の下方側に戸高方向に間隔を空けて設けられた上横桟としての横桟１７に接合した構成としている。このような構成とすれば、横桟１７によってパネル芯材１０の剛性を向上させることができる。また、補強材２１及びこれに嵌め込まれた縦桟材２０を共通部品として戸高寸法Ｈ１の異なる複数の戸パネル１に対して適用することができる。つまり、戸パネル１の横桟１７よりも上側部位の寸法を異ならせることで、戸高寸法Ｈ１の異なる戸パネル１を容易に実現することもできる。 Moreover, in this embodiment, the length dimension H4 of the vertical crosspiece 20 and the reinforcing material 21 is made into the mutually substantially the same dimension. That is, the vertical crosspiece 20 is not provided over the entire length of the door panel 1, but the length dimension H4 is smaller than the door height dimension H1 and is shifted toward the lower end side.
Further, the upper end portion of the vertical beam member 20 is joined to a horizontal beam 17 as an upper horizontal beam provided at an interval in the door height direction below the upper horizontal frame portion 12. If it is set as such a structure, the rigidity of the panel core material 10 can be improved with the crosspiece 17.
